With around 2,000 days to go until the Olympics start, research from Halifax Estate Agents shows London postal districts close to the 2012 Olympics site have risen by 15-20% on average since the International Olympic Committee awarded the games to the British capital in mid-2004. The rise equates to 7-8% a year, which is in line with London averages and around half the growth rate witnessed in prime London during the same period.

Since the announcement, Leytonstone, which rose by 23%, has been the fastest riser, adding £50,714 to the price of an average property. Hackney comes second with a 21% rise (£48,578) and Clapton picked up the bronze medal with an 18% (£38,895) increase.

However, Halifax Estate Agents economist Tim Crawford says: "Despite recent rises, there are eight postal districts close to the Games site where house prices are more than 25% below the London average.”

The cheapest place to buy near the 2012 Olympic site is Plaistow - with an average house price of £196,263. East Ham is second cheapest at £207,543 and Leyton comes in third at £210,599.
